    This engine is new I built it to use in my 87 Car, but time and age has caught up with me, So I decided to sell it.

    The following is what I did.
    Murcielago crank modified to work in Countach block. Crank only weighs around 40 lb vs the Countach crank at 60 or more.
    Crank is balance to "0" at each end
    Crower custom rods, balance to within .001 gr.
    Wisceo custom pistons to have 11 to 1 compression Pistons balanced to within .001 gr
    Special made sleeves allowing a 89.5 mm bore
    Intake and exhaust valves 5 mm over size, custom made.
    Kawasaki motor cycle valve springs, about 90 more seat tension.
    BMW valve adjusting shims, thinner than the Lambo part, therefore about 1/2 the weight.
    Use adjusting type shims from a 2 valve engine, again saving weight.
    Heads modified with oversize valve seats to work with the larger valves. All ports redone
    Ignition is COP by Electromotive Inc.
    Clutch is by RAM Automotive in Columbia, SC
    Cams were custom done by Iskenderian Racing Cams.
    Valve spring retainers are Titanium.
    Special custom made spring seats.

    Very cool "lump". Any idea about power difference between stock and now? Not a buyer just curious.

    Very cool idea though, a hot-rod Countach. :)
